Tungsten Carbide Straight Bore Nozzle – Gun Insert, 5/16″ Bore, 7/8″ Flange x 1-1/4″ Length

Part Number: 501-321
Category: Sandblasting & Abrasive Nozzles
Type: Tungsten Carbide Straight Bore Nozzle – Gun Insert, 5/16″ Bore, 7/8″ Flange x 1-1/4″ Length

The 501-321 Tungsten Carbide Straight Bore Nozzle is a compact, heavy-duty gun insert engineered for abrasive blasting applications that require increased media flow, precision, and extended service life. Featuring a 5/16″ straight bore with a 7/8″ flanged profile and 1-1/4″ overall length, this nozzle delivers a focused, consistent blast stream with greater throughput than smaller bores—ideal for controlled surface preparation and efficient material removal. Constructed from premium tungsten carbide, it offers exceptional resistance to abrasive wear, dramatically outlasting ceramic and steel nozzles in continuous-duty environments. Commonly used as an OEM replacement in Empire Abrasive systems, the 501-321 provides professional-grade performance for both maintenance and production blasting setups.
